Looks horrible! But if you add up all those mem% numbers it comes to
more than 100% so it is not as it appears. Also: 'free'
             total       used       free     shared    buffers    
cached
Mem:        256764     253292       3472          0       2904    
151692
-/+ buffers/cache:      98696     158068
Swap:       498004       1020     496984

I've only now touched swap. Don't know about memory leak or not, but
Mozilla isn't quite the pig I thought.
